Answer:

• On earth 73° of latitude is approximately equal to 8154.2 km.

,

• On earth 73° of latitude is approximately equal to 5096.4 mi.

Explanation:

The distance along a line of latitude is calculated using the formula:


D=(\theta)/(360\degree)*2\pi R\text{ where }\begin{cases}\theta=Angle\text{ of Latitude} \\ R=Radius\text{ of the earth}\end{cases}

Given: θ = 73°, R=6400 km

Then:


\begin{gathered} D=(73\degree)/(360\degree)*2*\pi*6400 \\ =8154.2\text{ km} \end{gathered}

On earth 73° of latitude is approximately equal to 8154.2 km.

When R=4000 mi.


\begin{gathered} D=(73\degree)/(360\degree)*2*\pi*4000 \\ \approx5096.4\text{ mi.} \end{gathered}

• On earth 73° of latitude is approximately equal to 5096.4 mi.
